Despite quantum's gains, standard computers still rule
Quantum computing is getting the headlines these days, with buzz among scientists of giga-powered number-crunching and unbreakable encryption.
NSA eyes encryption-breaking 'quantum' machine
The US National Security Agency is making strides toward building a "quantum computer" that could break nearly any kind of encryption, The Washington Post reported Thursday.
Research team's results make development of quantum computers more realistic
Together with a supporting research team, Kassel physicist Prof. Dr. Christiane Koch has made a discovery that is sure to attract significant attention among experts. Criteria established in the course of her research make ...
Laser beam orientation controls light's quantum properties
Quickly switching the orientation of a laser beam enables control over the quantum properties of light.
Behavior of ultra-cold atoms and polar molecules modeled
Theoretical physicist Ana Maria Rey uses the computer, as well as pencil and paper, to develop mathematical models that describe the behavior of ultra-cold atoms. The idea is to use these systems to learn ...
How losing information can benefit quantum computing
Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions ...
Student creates world's largest quantum cluster
(Phys.org) —Australian National University PhD student Seiji Armstrong has made a quantum leap towards next-generation computing.
X-ray vision for road diggers: The next quantum leap?
Quantum mechanics has been hailed as the next big thing in technology. And quantum computers are a media favourite. But there is a little-known quantum technology that can peer beneath the earth, which could ...
On-chip quantum buffer realized
Nippon Telegraph and Telephone Corp. has realized a quantum buffer integrated on an optical waveguide. The buffer is based on the "slow light effect", where the propagation speed of a pulsed light in a special ...
New material for quantum computing discovered out of the blue
A common blue pigment used in the £5 note could have an important role to play in the development of a quantum computer, according to a paper published today in the journal Nature.
Physicists aim to make transition to quantum world visible
Theoretical physicist Frank Wilhelm-Mauch and his research team at Saarland University have developed a mathematical model for a type of microscopic test lab that could provide new and deeper insight into ...
When scaling the quantum slopes, veer for the straight path
Like any task, there is an easy and a hard way to control atoms and molecules as quantum systems, which are driven by tailored radiation fields. More efficient methods for manipulating quantum systems could ...
Feynman wasn't joking: Modeling quantum dynamics with ground state wavefunctions
Scientists take a quieter step closer to first practical quantum computer
(Phys.org) —Scientists working to produce the world's fastest, most powerful computers have moved a step closer to creating a practical prototype using microwaves – by shielding the atoms driving this ...
